WILLIAM YOUNG, 0F KAYFORD, WEST VIRGINIA.

CAB-V7 HEEL.

Application filed January 10, 1911.

To all whom it may concern:

Be it known that I, WILLIAM YOUNG, citizen of the United States,residing at Kayford, in the county of Kanawha and State of lVestVirginia, have invented certain new and useful Improvements inCar-VVheels, of which the following is a specification.

The present invention relates to improvements in car wheels,'and isespecially applicable for use in connection with mining car wheels, ofthe type in which the wheel is free to revolve on the stationary axle.

The invention is designed to provide an improved construction in wheelsof this character whereby the life of the wheel and parts is prolonged;an easy running wheel is attained, and particularly, the wheel may beremoved or replaced with facility.

The invention resides mainly in the journal and journal hearing or hub,and the connection parts, and consists in certain novel features andcombinations and arrangements of the constituent elements, whereby thewheel is held on its journal.

In the accompanying drawing I have illustrated one example of thephysical embodiment of my invent-ion constructed according to the bestmode I have so far de vised for the practical application of theprinciples.

In the drawing: Figure 1 is a vertical central sectional view of a carwheel and journal, and the surrounding parts, and Fig. 2 is a transversesectional view on line 22 of Fig. 1.

As before stated the invention contemplates an improved mining oarwheel, and such a wheel is illustrated in Fig. 1 by the numeral 1. Thewheel is provided with the usual spokes 2, 2 and. the central. hub orjournal bearing 8, which is integral therewith. The journal is bored toform the seat 4, and at the inner side is counter-bored to form therecessed seat 5. At the outer side of the bearing, a cup 6 is extended,and externally threaded, for the reception of the screw cap 7. The axle8 is fashioned with the usual journal 9 and in addition has formedintegral therewith the enlarged annular projection or collar 10, adaptedto seat in the Specification of Letters Patent.

counterbore 9, thus providing against entrance of sand or grit to thejournal in its bearing.

As a means for securing the journal and journal bearing, and thus thewheel on the axle, I interpose the sectional collar 11, which may beapplied or removed at will. This collar is seated in an annular grooveor recess 12 provided in the journal 9. The sections of the collar arehinged together by means of the pin 13 which is passed through thecomplementary perforated ears of the adjoining ends of the sections. Thefree ends of the collar sections are formed, one with a tenon 14, andthe other with a complementary mortise 15, for holding the sections. Alook screw 16 may be provided, if necessary, for securing the tenon inits mortise and holding the sections rigidly together. The usual. oilhole 17 and screw plug 18 are present in the journal bearing, and toprovide a seat for the longitudinal frame bar 19, a lug or projection 20is formed integral with the axle 8.

In assembling the wheel on its axle, the wheel is first slipped over itsjournal 9, the recess 5 seating over the sand collar 10. he sectionalcollar 11, while in its open or ex tended position, is slipped over thereduced portion of the journal and seated in the groove 12. The ends ofthe collar are then clasped by the insertion of the tenon into itsmortise and securely clamped. about the grooved journal by turning thelock screw 16. It will be observed that the collar projects beyond theperiphery of the journal and is in loose contact with the shoulder 3 ofthe journal bearing or hub 3.

After the parts are assembled as described, the cap 7 is screwed overthe threaded extension 6, by means of a wrench placed over the squaredend 21 of the cap, and to lock the cap against accidental turning a pin22 may be inserted in complementary holes in the cap and extension, aswill. be understood.

From the above description taken in connection with the drawings, it isevident that I have produced an improved axle and wheel hearing whichfulfils the conditions set forth as the purpose of my invention.
